UK SMEs are optimistic about business prospects this year, according to research by UK data centre and communications specialist Node4. One in five decision makers have no concerns at all and expect to be prosperous and successful this year. Those that did have concerns, said IT topped their list (34%), followed by generating enough business (33%) and workforce retention (18%). The decision makers said that their existing IT infrastructure would not support business growth and that a lack of IT innovation would hold back success. The survey was held among 250 250 decision makers in companies between 50-500 employees.
